The roofed shelter included benches for players and an area for scorekeepers. It was partly open on its rink side.

The fire was reported at 6:35 p.m. on Aug. 4. When firefighters arrived, the shelter was fully involved. Fire officials put the damage estimate at $5,000. Some of the rink's boards next to the shelter suffered heat and smoke damage.

Grondahl ruled the fire as arson, since there were no other sources of ignition present.
